- Abstract:
-
The phenylene acrylic emulsion was modified with octamethylcyclotetrasiloxane, vinyl cyclotetrasiloxane and propylene trifluoroacetate, and the appropriate amount of modified monomer and the silicone/fluorine ratio were determined. The infrared spectrum of the emulsion showed that the silicone/fluorine-modified styrene acrylic emulsion was obtained. The effects of silicone and fluorine on the stability of polymerization system, the performance of emulsion coating film and reaction speed were studied. The results showed that with the increase of the content of modified monomers, the reaction speed decreased. When the mass fraction of modified monomer in the control system ≤15%, the ratio of octamethylcyclotetrasiloxane, vinyl cyclotetrasiloxane and propylene trifluoroacetate had no effect on the stability of the emulsion.
